MACHINE FOR CUTTING ICE.

SPECIFICATION forming part of Letters Patent No. 418,351, dated December 31, 1889.

Application filed August 17, 1888.

To all whom it may concern:

Be it known that I, DANIEL A. I-IAINEs, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Cutting Ice; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in ice-cutting machines; and it consists of the combination of devices and construction and arrangement of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a plan view of my improved ice-cutting machine constructed in accordance with my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical sectional view through the apparatus or machine on the plane indicated by the irregular line 00 of Fig. 1. Fig. I is an end elevation of the ma chine, looking at the front end thereof. Fig. 5 is a detail view illustrating the means for supporting and adjusting the steering-wheel.

To construct an ice-cutting machine in accordance with my invention, I provide a set of runners or pair of skids a, and mount thereon a small reversible engine Z) and steamboiler 0), together with all necessary equipments to put the engine in working or running order. At the forward ends of these skids a, is a hinged frame 0, which is pivotally connected at its rear end to a shaft 7c by means of arms 7t, which are secured to the frame and fitted loosely on the shaft, so that said frame is capable of being revolved about its pivotal point. This frame 0 rests and travels, when the machine is in use, on the surface of the ice, as thelower side of the frame is extended below the pivot 0' thereof, (see Fig. 3,) and the frame may be held at any desired elevation by means of a set-screw Serial No. 282,967. (No model.)

guide-bar c, which is fixed at one end to one of the skids and projects forward beyond said skid, the guide-bar being curved so that the clamp or box d will readily slide over the same when the frame is raised. Mounted on this frame 0, in proper bearings h, is a shaft f, having secured to one end of the same a large circular cutter g, which is given a rapid motion by a small pinion i meshing with a large toothed wheel j, secured to the driving-shaft k of the engine I). At the rear of the skids a is a shaft Z, mounted on bearings m, capable of being moved vertically ashort distance, as clearly indicated in Fig. 5 of the drawings. This shaft Z carries two wheels 42, each provided with a series of projecting barbs or spikes 0, which, when the wheels at are revolved, engage with the ice 011 which the machine rests and propel the apparatus forward. A lever n, spanning the two wheels n and secured to the shaft 1, serves as a convenient means for readily lifting the wheels n and thus disengaging the barbs o from the ice. Back of the engine I) is a short shaft 19, suitably mounted in bearings 19', having attached to one end a large toothed wheel g, which meshes with a pinion s, secured to the driving-shaft of the engine I), which arrangement gives the said shaft 19 a slow powerful rotary movement. Attached to one of the extremities of this shaft p is a small chain-belt wheel r, which is engaged with a similar wheel 25, attached to the verticallymoving shaft Z, which arrangement will give the necessary rotary movement to the spiked wheels n for propelling the machine forward. Mounted in a suitable position on the skids a isatank a, properly connected with the fire-box of the boiler 11 by small pipes or tubes w, provided with suitable valves for regulating and controlling the fiow of a gaseous vapor generated in the tank a from gasoline, oil, or other substance. The object of this tank a is to provide the boiler o with a suitable fuel for generating steam. Hinged to one of the skids a is a guide-plate as, for properlysteering the apparatus, which consists of a plate 00, secured in a vertical position some distance away from the side of the skid a,to which it is at tached.

In operation the cutter g is given a rapid rotary motion and the frame 0 allowed to rest on the ice. By the rotary movement of the wheels the machine is propelled forward, the cutter g making an incision in the ice. After the first out has been made the guide-platea:

is placed in the incision,which steers the apparatus and cuts the ice in parallel lines.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In an ice-cutting machine, the combination of the skids, a motor mounted thereon and having the shaft 70, a vertically-adj ustable frame 0, carried by the arms 70' and adapted, when lowered, to lie in the plane of the skids and to travel on the surface of the ice, a sawarbor journaled in the vertically-adjustable frame and geared directly to the shaft 70, on which said frame is pivoted, an upright arched arm secured to the skids and extending between the sides of the adjustable frame, I

and a clamp carried by the adjustable frame at or near its outer end and fitted on the arched arm to hold the frame in a fixed po- I sition thereon, all arranged and combined substantially as described, and for the purpose set forth.

2. In a machine for cutting ice, the combination of the skids, a motor m0unted.there.

on, a crank-shaft 7c, driven by the motor, an adjustable frame having a saw-mandrel which is geared directly to the shaft k, a propelling-wheel mounted on the skids at one .end, and an intermediate counter-shaft p,

geared to the shaft 70 and to the shaft of the propelling-Wheel, whereby the saw-mandrel and the propelling-wheel are rotated from a common motor, substantially as described.

3. In a machine for cutting ice, the combination, with the skids, of a horizontal lever 'n, fulcrumed at one end of the same, the ver tically-sliding bearings fitted in fixed seg- DANIEL A. I-IAINES. [n 8.]
